概括
蛋的颜色和半透明度会影响家禽的生产. 较深的蛋和更高的半透明度得分与化能力和小体重的增加相关,但更薄. 这些特征为肉养殖群管理提供了非侵入性指标.
科学领域:
- 禽畜科学 禽畜科学 禽畜科学
- 动物育种 动物育种
- 化场管理管理
背景情况:
- 成功化对于家禽产业的经济至关重要.
- 蛋的特点,如半透明度和颜色,可能会影响化能力和的质量.
- 了解这些关系可以优化肉养殖者群体的表现.
研究的目的:
- 为了研究蛋半透明度 (T评分) 和轻度 (L*值) 对蛋厚度,化能力和小体重的影响.
- 为了确定这些蛋特征是否可以作为预测化结果的非侵入性指标.
- 为改善 brojiler繁殖者群体管理策略提供数据.
主要方法:
- 利用了来自商业Ross 708繁殖群 (50-55周大) 的4320个蛋.
- 使用3分主观评分系统 (T评分) 评估蛋半透明度.
- 用电子色度计测量蛋外的轻度 (L*值),将蛋分类为明亮或黑暗.
- 使用SAS (V9.4) 与GLIMMIX程序以及Tukey的HSD测试 (P ≤0.05) 分析的数据.
主要成果:
- 较深色的蛋比较重,化能力高3.8%,外厚度比较轻的蛋高6微米.
- 较高的半透明度得分 (T评分1) 与转移时更重的卵子重量和6.9%更大的化能力有关.
- 与T分数2和3相比,T分数1的蛋的外明显较薄 (28-34微米).
- 一个相互作用表明,T分数为1的明亮蛋的外比T分数为3的深色蛋更薄.
结论:
- 蛋的半透明度和轻度是蛋厚度,化能力和小体重的可靠的非侵入性指标.
- 较深的蛋与更好的化能力和更厚的贝有关.
- 半透明度得分会影响化能力和小的体重,但与外厚度相反.

Background and Environment Affect Phenotype
6.6K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Complementation Tests
5.0K
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...
